My preference is as follows:

1) Don't personally care for the loli units, so if they never show up I'm ok with that.
2) A week off after every 2 events would be ideal to level/raise affection on new units.
3) Gold rush! Now that the barracks have been introduced it's the perfect time for Gold Rushes to begin.
4) Revivals would be excellent. I never got the chance to get Belinda or Anya, and my Echidna and Maribel are both very weak.
5) Awakening!
6) The Dark Knight event! We arm to have skipped this one and I'd really like to try it.
7) Please add the new story missions!
8) Finally, a sale on sacred crystals would be pretty nice.

Thank you for taking our feedback! I am in general happy with the product as it is, I'd just like some more time between events to enhance my new units.
